Class AbsRectAnimation

      com.miginfocom.ashape.animation.animations.AbsRectAnimation

All Implemented Interfaces:

Animation, java.io.Serializable

public class AbsRectAnimation
extends AbstractAnimation

An animation that animates between two AbsRect objects. They need to be per argument compatible. I.e if the width is an Integer in the first AbsRect it needs to be that in the second as well. The reason for this is that we don't have the relative size values that has to be used to convert relative values to absolute.

Constructor Detail

AbsRectAnimation

public AbsRectAnimation(AbsRect sRect,
                        AbsRect eRect)

Constructor without cached objects. Creates new on-the-fly for every call. This can be expensive and may create a lot of garbage.

Parameters:

sRect - The source, or start, rectangle.

eRect - The destination, or end, rectangle.

AbsRectAnimation

public AbsRectAnimation(AbsRect sRect,
                        AbsRect eRect,
                        int cacheFrameCount)

Constructor.

Parameters:

sRect - The source, or start, rectangle.

eRect - The destination, or end, rectangle.

cacheFrameCount - How many frames that should be cached, and used. 0 means "no caching".

Method Detail

createObject

public java.lang.Object createObject(float d)

Description copied from class: AbstractAnimation

Returns a newly created object that complies to the same rules as AbstractAnimation.getObject(float). For subclasses to implement.

Specified by:

createObject in class AbstractAnimation

Parameters:

d - 0.0 to 1.0 0.0 is the first Object/frame and 1.0 is the last.

Returns:

A newly created object that complies to the same rules as AbstractAnimation.getObject(float).

getInsets

protected java.awt.Insets getInsets(java.awt.Insets i1,
                                    java.awt.Insets i2,
                                    float d)

Returns an Insets object that lays distance d (0..1) between both arguments.

Parameters:

i1 - First Insets, may be null.

i2 - Second Insets, may be null.

d - 0..1 Where 0.0 will return i1 and 1.0 will return i2. Values in between are interpolated.

Returns:

An newly created Insets object that lies distance d (0..1) between both arguments. May be null.

checkRects

protected boolean checkRects(AbsRect r1,
                             AbsRect r2)

Check so that x, y, w, h of the argument rectangles are of same type.

Parameters:

r1 - The first rect

r2 - The second rect

Returns:

true if they are compatible for animation.

getStartRect

public PlaceRect getStartRect()

Returns the start AbsRect.

Returns:

The start AbsRect.

getEndRect

public PlaceRect getEndRect()

Returns the end AbsRect.

Returns:

The end AbsRect.

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class AbstractAnimation
